The Multi-Frequency Recirculating Planar Magnetron (MFRPM) is a variant of the Recirculating Planar Magnetron, a crossed-field, high power microwave source1. The MFRPM integrates the same advantages over traditional cylindrical cavity magnetrons as UM's original RPM with the added benefit of producing multiple frequencies using a single HPM device. Previous research involved the design and fabrication...
Multipactor breakdown on a dielectric may provide automatic protective isolation of electronic circuits such as transmitter-receiver (TR) switches in radar. Prior Monte Carlo simulations suggest the application of a DC bias across a dielectric window in a vacuum-gas environment can lower the threshold for the onset of RF-initiated multipactor1. Variation of the DC bias may therefore provide a mechanism...
The Recirculating Planar Magnetron (RPM) is a crossed-field device which presents numerous advantages in generating HPM. A 12-cavity, conventional-polarity, 1GHz model was designed and tested at a −300 kV, 0.3–0.5 microsecond pulselength and a 0.3 T axial magnetic field. The initial design and experimental results are discussed.
The Recirculating Planar Magnetron (RPM) is a novel crossed-field device whose geometry is expected to reduce thermal load, enhance current yield as well as ease the geometric limitations in scaling to high RF frequencies as compared to the conventional cylindrical magnetrons.
